A bug in Version 4.4.2

Dear colleagues,

it shows an error: “2 configuration errors found”. These “syntax errors” actually fires up at the field named “Additional Headers”: http://i.imgur.com/5oThukF.png

The form works, and as far as we can see the syntax like
Reply-To: [your-email] is pretty correct one.

So it works, but the error message is very annoying for the most of the perfectionists 🙂 Is it fixable? Thank you!
